A negative test with a quadruple test strip eight weeks after a high risk test will most likely rule out the possibility of AIDS, but may be inaccurate and will require a trip to the hospital for testing.
IV test strips are an HIV test that detects both HIV antigen and HIV antibodies. A negative test result on the HIV quadruple test paper in the eighth week after high-risk sex is a good indication that the blood does not contain HIV antibodies, and the possibility of AIDS can be ruled out with a high degree of probability.
However, there is a window period for HIV testing, and the use of the test strips is affected by a number of factors, such as personal errors or quality problems with the test strips, which may lead to errors in the results, so HIV infection cannot be completely ruled out.
The test results cannot be used as a basis for diagnosis or exclusion of AIDS, and you need to go to the hospital or CDC for another test to confirm.
